HEAT DEFLECTOR.

Application tiled November 12, 1926. Serial No. 148.023.

tain thevair filter thereof in the path of heat f passing throu h the deflector.-A A further o ject of this invention resides in the rovision of a heat delector having an air ter which is constructed of air penetrating rmaterial 'preferably formed in sheets. a

A still further object of this invention resides in the provision of a heat dedector having an air filter formed of steel wool coated withiibrous asbestos so as to permit air to pass therethrough.

ln addition to the foregoing objects, this invention resides in the provision of a heat deector embodying an air filter associated with the dedector so as to deiiect soot coming in contact therewith into a catch basin. Aside from the aforesaid objects, this invention resides in the provision of a heat dedector having an air filter which is associated with an adjustable baille plate adapted to be utilized to cover the heat register or other similar unit heating systems when it is desired to shut off the heat.

Among the many objects of this invention is the rovision of the particularly constructed associated with the deflector to not only lter air passing through the material supported thereby, but to `permit the natural dow of heat from the heat distributing unit .with which it is associated should the filter become clogged.

Included among the salient features of this invention is the provision of an air filter` adapted to present fibrous materlal 1n the path of airto be filtered, the s ame protruding om ns so as to permit a1r to pass therethrough and foreignV matterA to be checked thereby for deposit on the fins.

With these and other objects in view, this invention resides in certainnovel 'features of construction, arrangement and combiter elements, the same being.

in the speciiicatiom'illustrated -in the accompanying drawings and ointed out in the appended claims and, w ile the disclosure depicts my present conception of the invention, the right is reserved to make such changes in the construction as come within the scope of the claims.

In the accompanying drawings: f Fig. l is a sectional view through a hea deector constructed in accordance with my invention;

In the present embodiment of this invention, the letter P designates a iioor register of a building heating plant, not shown, and while this type of heat emitting unit is herewith shown, the deflector is adapted to be associated with any type of heat emitting unit of building heating systems or heat discharging devices.

Associated with the register P is a heat form deilector 5 preferably having an inlet port 6 and outlet port 7, the formerof which has an adjusting baffle 8 `.associated therewith for eitherdirecting the iiow of heat, entering the port 6, toward the outlet port 7 in various volumes, or to seal the inlet port so as .to entirely prevent heat from entering the deflector. 'i

Associated with the inlet and outlet ports of the deector is a stationary deiector plate 9 adapted to direct heat toward the latter ort. v -p Coverin the outlet port 7 is a sheet of reticulate material R of fine mesh adapted to conceal lthe interior of the deflector"y and prevent soot or other foreign material in the heated air from passing into the building should it escape a filter 10 disposed to its rear and within the deflector.

The aforesaid filter 10 referably consists of forwardly and rearwardly disposed grates Fig. 3 is a sectional view online 3-3 of l 11 and 12, the former of which preferably p therewith, so as to removably accommodate a sheet of filtering material 13. The vertically and horizontally disposed bars, after the `filtering material has been placed therebetween, are locked together by suitable fastening elements 14.

Beneath the filter 10 a catch basin 15 of any suitable constructionl is disposed, the same being adapted to catch foreign matter separated from the heated air by the filter.

The aforesaid filter is disposed within the deflector in spaced relation to certain walls thereof as shown at 16, so as to permit air to pass around the filter and maintain its initial velocity, especially should the filter become clogged by an excess accumulation of'foreign matter.

rTo facilitate continuous circulation and purification of the air in a room, the de- Hector is provided with air inlet ports 17, the same preferably bein disposed at the base of its front and si e walls, althou h they may be otherwise associated with t e components of the deflector where alterations of the deilector are necessary to associate it with different types of heat distributin units.

The terin material 13 is preferably formed in shee comprising a suitable grade 4of steel wool 18 coated with asbestos fibers 19, the same being xed on the surfaces of the steel'wool by any suitable adhesive so as to permit air to readily pass therethrough. In the modified form of filter shown in.

fins are adapted to carry fibrous asbestos 32l or other suitable material in protruding relation thereto, soa's to permit air to readily pass throu h the same and allowA foreign matter, 4suc as soot or the like, to fall on the fins. With the fins 31 projecting down-v wardly from the sheet of material 30 and supporting the asbestos therebetween as t aforesaid, the foreign matter cheeked by the asbestos will notbank'a of the sheet 30, therefore casing and adapte inst the surfalclne. ee p of t e filtered air is permitted through ie sheetl the rooms of bui dings and, through the utilization of the particular filtering element and associated retaining adjuncts' thereto, a high degree of purification is maintained at a minimum cost.

I claim and desire to protect by Letters Patent is:- A Y 1. A device of the cla-ss described comprising a casing having an inlet opening in its bottom and an outlet opening in one side thereof, a baiiie ad'ustably arranged in the in one position to close the inlet opening and in another position to direct the air from the inlet opening toward the outlet opening, a curved balile plate extendin over portions of the t'op and the rear wall o the casing for delecting air through the outlet opening, a filterin medium suspended from the top of t e casing and spaced from the outlet opening with its lower end terminating short of the bottom of the casing and a pan at the bottom of the casing and arranged under the filtering medium for gceiving particles of foreign matter there- Having thus described my invention, whatV 2. A device of the class described comprising a casing having an inlet opening in its bottom and an outlet opening in one side thereof, a baille ad'ustably arranged in the casing and adapted in one position to close the inlet opening and in another position to direct the air from the inlet opening toward the outlet opening, a curved afile late extending over portions ofthe top an the rear wall of-the casing for deiecting air through the outlet opening, a iltering'medium sus- -pended from the top of the casing and spaced rom -the outlet opening with its lower end terminating short of the bottom vof the cas-A ing, a pan at the bottom ofthe casin and arranged under the filtering medium or receiving (particles of foreign matter therefrom an said casingi having an air inlet sage extending through the wall in w ich the outlet openin is arranged and communicating with t e interior of the casing, said opening passing under the pan.

In testimony whereof I aflix m signature.
